Again the biggest issue was my order was shipped UPS. I have had stuff shipped from California by USPS to N.H. & it took 3 dyas to my P.O. Box UPS takes 5 days.The cartridge is same quality as far as I can tell & the only way to improve it is to lower the price. I find it works just as well as the overpriced HP cartidges.I DO Recommend the Linkyo brand.

It didn't seem to work nearly as well as the actual HP ink. I'm not sure if I will even be able to use them.

I buy a lot of ink cartridges from LINKYO, most are very good but some are problematic, but generally I'm pleased.

How to make sure the C9351AN#140 is right for your HP printer model

Concerned about compatibility because your HP printer isn�t listed on the box of your newly purchased ink/toner cartridge?
While the packaging of the ink/toner cartridge may list some compatible printers, manufacturers are unable to include an exhaustive list due to space limitations.
Watch the video to see how you can take advantage of the information on SuperMediaStore.com to help you confirm once and for all whether your
ink/toner cartridge will fit your HP printer.
